Experts recommend closer scrutiny of radiation exposure from CT scans
Date:11/28/2012

nted out that because there is a high background incidence of cancer worldwide, the small incremental increase in cancer that may be attributable to low doses of radiation from medical imaging is extremely difficult to ascertain. They stated that national and international registries that track cancers and patient exposures to medical radiation may one day make it possible to conduct large epidemiological studies that could help make such associations.

"In reaction to media coverage of radiation overexposure cases, some patients refuse to undergo medical imaging procedures," said Boone. "Yet for almost all patients, the risks of foregoing a needed medical procedure far outweigh any potential radiation-associated risks."

Even accurately recording patient exposures of radiation from medical imaging is extremely difficult, according to the authors. Although it is easy to ascertain how much radiation a machine administers during an imaging study, the amount actually received by a patient depends on various factors including body size. For example, because of differences in body mass, children and small adults can receive a dose of radiation two to three times that of larger people, even when the dose administered is the same.

Other factors, such as whether the patient lies on a moving or stationary table, also affect the radiation dose received. Federally sponsored research is needed to develop methods to more accurately measure patient exposures from different types of CT scans, the authors suggested.

Summit participants also discussed the role of human error in CT scanning, which has resulted in widely publicized instances of radiation overexposure. They point out that CT operators frequently are responsible for several machines made by different manufacturers, each of which may utilize dissimilar nomenclature and control consoles, thereby increasing the chance for error.
